No full textDiamysis mesohalobia Ariani & Wittmann, 2000 Figs 14, 15 Diagnosis (sensu lato: covering the three currently known subspecies). Appendix masculina 80–120% the length of terminal segment of antennular peduncle (Fig. 14 B). Eyes normal; eyestalks with fenestra paracornealis weakly developed (Fig. 15 K) or absent (Fig. 15 A), in any case mostly not or poorly visible. Distal segment of maxillary palpus with 4–27 distinct denticles. Presence of fringes on male carapace varies between subspecies; no such fringes in females. Basal segment of thoracic exopods with outer corner spiniform or less frequently ending in an acute edge, occasionally rounded in the first and/or in some of the median and/or posterior exopods. All pereiopods with normal carpopropodus and slender, styliform claw (Figs 14 E, 15B, M). Carpopropodus of thoracic endopods 3–8 with 3 (2; 4), 3–2 (4), 3–2, 2–3, 2–3 and 3–2 segments, respectively. Carpopropodus of endopod 3, if 3- segmented, with basal segment not longer than remaining segments combined (Fig. 15 M). Thoracic endopod 3 and often also endopod 8 with at least one among the four paradactylar setae distally pectinate in (most) females, smooth or pectinate in males. Male pleopod 4 biramous with 2-segmented sympod and with small, 2-segmented endopod (Figs 14 H, 15N); its exopod 2–(3)-segmented, with large modified seta at tip. This exopod with basal segment bearing a smaller smooth seta (Figs 14 H, 15D), in certain populations occasionally with an additional barbed seta (Fig. 15 N). Endopod of uropod with one strong spine below statocyst, statolith composed of vaterite. Telson subquadrangular (Fig. 15 S) to subtriangular (Fig. 15 J); maximum width is 1.4–3.0 times that at apex; its apical cleft with 8–39 laminae; cleft is 5–26% telson length. Taxonomy. Interbreeding experiments by Ariani & Wittmann (2000) indicated mutual crossability between morphologically different Mediterranean populations of D. mesohalobia. The three main morphotypes distinguished were, therefore, described at subspecific level as D. mesohalobia mesohalobia Ariani & Wittmann, 2000, D. mesohalobia gracilipes Ariani & Wittmann, 2000, and D. mesohalobia heterandra Ariani & Wittmann, 2000; each of these subspecies are treated in separate subchapters below. Occurrence (Fig. 16). Marine, brackish and fresh (near)-coastal waters of the E-Mediterranean and Marmora Seas.Published as part of Wittmann, Karl J., Ariani, Antonio P. & Daneliya, Mikhail, 2016, The Mysidae (Crustacea: Peracarida: Mysida) in fresh and oligohaline waters of the Mediterranean.

Mainly in the western Mediterranean: along the coasts of the Tyrrhenian, Sardinian and Ligurian Seas, Golfe du Lion, Strait of Messina; rare in the eastern Mediterranean: Island of Crete in the Aegean Sea. The populations at the Atlantic coasts of southern Spain and Portugal may have originated from Mediterranean lagoons by transfer in ballast water (Cunha <i>et al.</i> 2000: as <i>D. bahirensis</i>), although an indigenous status of the Atlantic populations is not excluded (Wittmann & Ariani 2012a). Type locality is the mixoeuhaline to weakly metahaline lagoon Lago di Caprolace at the Lazio coast, Tyrrhenian Sea. The species is mostly found in mixoeuhaline to metahaline lagoons, also in marine coastal habitats as well as mesohaline to mixoeuhaline reaches of estuaries.

Material examined. 84 samples from mesohaline to mixoeuhaline coastal waters of the Adriatic, Aegean and Levantine Seas (Ariani & Wittmann 2000). Previously unpublished sample: 93 F ad. 5.5–7.1 mm, 223 M ad. 4.3– 6.3 mm, 22 subad., 56 imm., 112 juv., karstic spring with small salinity fluctuations, Fiume Piccolo, near Torre Canne, Adriatic coast of southern Italy, 40.8275N 017.4818E, 2–3 m depth, striped with hand net from brown algae, S = 15, pH 7, 18.5°C, 29 Nov. 2011, leg. A. P. Ariani. One specimen of this sample reminds of a gynandromorph of the 'fore and aft' type (Hollingsworth 1960): with pleopods as typical for adult males, but antennula without appendix masculina and also without plumose setae typical of males or females. Short updated description. The following data cover primarily the type population in the mesohaline spring Fiume Morello (Apulia, Adriatic Sea). Data from remaining populations, as far as different, are given in square brackets. Diamysis mesohalobia with short rostrum forming a wide convex angle with rounded tip (Figs 14 A, C). Fenestra paracornealis poorly developed, rarely visible. Carapace without fringes (Fig. 14 C) in both sexes. Palpus of maxilla with subcircular terminal segment, armed with 6–24 [5–24] denticles along distal margin. Basal segment of thoracic exopods with outer corner spiniform (Fig. 14 D), less frequently ending in an acute or rounded edge, especially in posterior exopods. Pereiopods relatively short, endopod 8, when stretched anteriorly, extending to basis of endopod 1 or at most up to maxillae [mandibles]. Pereiopods stout (Fig. 14 E) to moderately slender, with R6 = 4.4–6.1 [4.4–6.8]. Carpopropodus of thoracic endopods 3–8 with 3 (2), 3 (2), 3–2, 2–3, 2–3, and 3 (2) [3–2] segments, respectively. Thoracic endopod 3 with carpopropodus being longer than 5 times its maximum width; thoracic endopods 3–8 with long and slender claw. Penis with smooth setae only, arranged in a semicircle close to ejaculatory opening (Fig. 14 F). Male pleopod 4 biramous with 2-segmented exopod bearing a modified, strong seta at tip and a smaller, smooth seta subterminally on basal segment (Fig. 14 H). Scutellum paracaudale subtriangular, biconvex; tip pointed or less frequently rounded (Fig. 14 J–M). Telson subquadrangular (Fig. 14 N) [to subtriangular], 0.8–0.9 [0.7–1.0] times length of last abdominal somite; maximum width of telson is 1.6–2.0 [1.6– 3.0] times that at apex; lateral margins concave or rarely straight, armed with 7–12 [7–14] spines. Apical cleft of telson with convex (Fig. 14 N) or rarely straight margins, bottom of cleft rounded, cleft is 12–16% [9–16%] telson length, cleft lined by 15–39 [8–39] laminae. Body length: Adult females 4.6–9.6 mm, males 4.1–7.7 mm. Distribution (Fig. 16). Eastern Mediterranean only: in Adriatic, Aegean, and Levantine Seas. Mostly in mesohaline karstic springs with small salinity fluctuations, also in mesohaline to mixoeuhaline lagoons and estuaries. Predominantly in the salinity range 10–38, locally down to S = 2. Samples of this subspecies were taken by Özbek et al. (2004) in the Köyceğiz lagoon at the Aegean coast of Turkey. Data by Akin et al. (2005) and own measurements at the northern shore (S = 2.3 in 0.5–2 m, 10 June 2006) suggest that the positive station was most likely from the oligohaline range within this large, oligo- to metahaline lagoon with complex salinity patterns.Published as part of Wittmann, Karl J., Ariani, Antonio P. & Daneliya, Mikhail, 2016, The Mysidae (Crustacea: Peracarida: Mysida) in fresh and oligohaline waters of the Mediterranean.

Material examined. 42 samples from oligohaline to metahaline lagoons and karstic springs in diverse parts of the eastern Mediterranean plus 13 samples from freshwater tributaries of the Adriatic Sea, see Ariani & Wittmann (2000) and Wittmann & Ariani (2012b); material studied by Holmquist (1955), previously unpublished reexamination: dissected parts of 1 M ad. 8 mm, 2 egged F ad. with body length 7 or 9 mm, respectively, on a total of 3 slides labelled " Diamysis biharensis. Herzegovina & Timavo, det. Ch. Holmquist, prep. 57–59", SMNH reg. nos. 140108 – 140110. According to Holmquist (1955) this material was collected by Janez Hoenigman in Lake Deran, 2–5 m depth, 27 Apr. 1954, 43.04N 017.75E, Herzegovina, altitude 0 m, sea distance 31 km as calculated along the small effluent and following this along the Neretva River to the east coast of the Adriatic Sea. Short updated description. The following data covers primarily the type population in an oligo- to mixoeuhaline lagoon with brackish spring, Limni Antinioti (Island of Corfu, Ionian Sea). Data from remaining populations, as far as different, are given in square brackets. Diamysis mesohalobia with short rostrum mostly forming a wide convex angle with broadly rounded tip (Fig. 15 K, L). Fenestra paracornealis weakly developed, mostly visible (Fig. 15 K) in well preserved material [mostly visible in well preserved material from Lake Deran (near E-Adriatic coast) or rarely from Schiavetti Springs (Gulf of Trieste, N-Adriatic)]. Carapace of adult males with fringes arranged in two submedian stripes plus one subterminal stripe (Fig. 15 K, L). The submedian stripes may be differentiated as two separate stripes each (Fig. 15 K). Palpus of maxilla with subcircular terminal segment, armed with 8–27 denticles along distal margin. Basal segment of all thoracic exopods normally with spiniform outer corner, rounded only in some of the posterior exopods of small individuals ( 6 mm) often with a minute additional seta; basal segment subterminally with a smooth seta (Fig. 15 N–P). Large males (> 7 mm) with 0–1 [0–4] additional small barbed [and/or smooth] seta (Fig. 15 N, P) on terminal margin of basal segment of exopod. Scutellum paracaudale subtriangular, mostly biconvex [or with upper margin convex and lower margin concave]; tip pointed (Fig. 15 Q, R) or less frequently rounded, rarely bifid. These margins mainly smooth in small specimens [or undulate in large ones (> 8 mm; Fig. 15 Q)]. Telson mostly subquadrangular (Fig. 15 S), but subtriangular in small specimens (<6 mm), 0.7–0.9 [0.7–1.0] times length of last abdominal somite; lateral margins concave [to straight], armed with 8–13 [6–11] spines; maximum width of telson is 1.8–2.4 [1.4–2.4] times that at apex; its apical cleft with straight to strongly convex margins. Bottom of cleft angular to rounded. Cleft is 10–19% [10–26%] telson length, cleft lined by 12–31 [9–38] laminae (Fig. 15 S). Body length. Adult females 3.7–9.7 mm, males 3.0– 8.7 mm. Distribution (Figs 12, 16). In fresh and brackish waters of springs, estuaries, lagoons, and lakes all around the Adriatic Sea (Fig. 12), salinity range S = 0–42. Outside the Adriatic (Fig. 16) known only from oligo- to polyhaline waters on the coasts of the Ionian and Marmora Seas, so far not from fresh-water (Ariani & Wittmann 2000, Wittmann & Ariani 2012a, b).Published as part of Wittmann, Karl J., Ariani, Antonio P. & Daneliya, Mikhail, 2016, The Mysidae (Crustacea: Peracarida: Mysida) in fresh and oligohaline waters of the Mediterranean.

Anticipation of novelty recruits reward system and hippocampus while promoting recollection
No full textThe dopaminergic midbrain, which comprises the substantia nigra and ventral tegmental area (SN/VTA), plays a central role in reward processing. This region is also activated by novel stimuli, raising the possibility that novelty and reward have shared functional properties. It is currently unclear whether functional aspects of reward processing in the SN/VTA, namely, activation by unexpected rewards and cues that predict reward, also characterise novelty processing. To address this question, we conducted an fMRI experiment during which subjects viewed symbolic cues that predicted either novel or familiar images of scenes with 75% validity. We show that SN/VTA was activated by cues predicting novel images as well as by unexpected novel images that followed familiarity-predictive cues, an 'unexpected novelty' response. The hippocampus, a region implicated in detecting and encoding novel stimuli, showed an anticipatory novelty response but differed from the response profile of SN/VTA in responding at outcome to expected and 'unexpected' novelty. In a behavioural extension of the experiment, recollection increased relative to familiarity when comparing delayed recognition memory for anticipated novel stimuli with unexpected novel stimuli. These data reveal commonalities in SN/VTA responses to anticipating reward and anticipating novel stimuli. We suggest that this anticipatory response codes a motivational exploratory novelty signal that, together with anticipatory activation of the hippocampus, leads to enhanced encoding of novel events. In more general terms, the data suggest that dopaminergic processing of novelty might be important in driving exploration of new environments
